There are still a lot of RHEL/CentOS 5 users out there, which run python 2.4. While py3 is moving forward, the number of users stuck on 2.4 is still considerably larger, and we will continue to support that until such a time as it's no longer the case. In the meantime, we are exploring options so that we can help those on newer distributions work by default in the same way.
